Abstract:

Relying on abundant local cattle resources, Yunnan has cultivated excellent varieties such as Yunling cattle adapted to the ecology of the south, promoted industrial development through policy support and technology promotion, and established three breeding systems with the protection and quality improvement of local varieties, the innovation and efficiency of independent breeding varieties, and the introduction of variety localization as the core. At present, Yunnan has initially formed an integrated industrial chain of breeding, breeding, processing, and sales; the coverage of improved varieties has increased, and the effects of brand building and industrial integration have begun to show. However, it still faces multiple constraints, such as insufficient independent innovation ability of the seed industry, scattered breeding modes, imperfect industrial chain, weak factor guarantee, and challenges of epidemic prevention and control. In the future, efforts should be made to improve the breeding system, promote large-scale breeding, extend the industrial chain, strengthen policy support and improve supervision, so as to promote the transformation and upgrading of the beef cattle industry and achieve high-quality development.
